# All Text Analytics

[Text Analytics](https://docs.catalyst.zoho.com/ja/zia-services/help/text-analytics/introduction)は、前のセクションで説明した3つの機能すべてを組み合わせたものです：**Sentiment Analysis**、**Named Entity Recognition**、および**Keyword Extraction**。特定のテキストブロックに対してこれら3つのアクションすべてを実行し、テキストのトーン、そこから認識されたエンティティの分類、およびテキストの要旨を提供するキーワードやフレーズを取得できます。

以下に示すように、1回のリクエストで最大**1500文字**のテキストブロックを入力として渡すことができます。テキストは`getTextAnalytics()`に渡されます。また、それらのキーワードを含む文に対してのみSentiment Analysisを実行するためのオプションのキーワードを渡すこともできます。

レスポンスには、各テキスト分析機能の結果が含まれます。それぞれの機能と応答の詳細については、各機能のページを参照してください。

以下で使用されている`zia`リファレンスは、
[コンポーネントインスタンスページ](https://docs.catalyst.zoho.com/ja/sdk/nodejs/v2/zia-services/get-component-instance)で定義されています。

```javascript
zia.getTextAnalytics(['Zoho Corporation, is an Indian multinational technology company that makes web-based business tools. It is best known for Zoho Office Suite. The company was founded by Sridhar Vembu and Tony Thomas and has a presence in seven locations with its global headquarters in Chennai, India, and corporate headquarters in Pleasanton, California.'], ['Zoho']) 
//入力テキストを渡す for all Text Analytics, and the keywords for Sentiment Analysis
	.then((result) => console.log(result))
	.catch((error) => console.log(error));
```
